Geological Provenance – Kem Kem Beds, Tegana Formation
This fossil originates from the Tegana Formation within the Kem Kem Basin of southeastern Morocco, a globally recognised fossil locality. These deposits date to the Upper Cretaceous period, specifically the Cenomanian stage, approximately 95 to 100 million years ago. The Kem Kem Beds are composed primarily of fluvial sandstones and siltstones formed within ancient river systems, floodplains, and deltaic environments. This region is renowned for preserving a diverse range of vertebrate fossils, including large theropods, crocodyliforms, fish, and other prehistoric life.

Species Identification – Spinosaurus aegyptiacus
This tooth is attributed to Spinosaurus aegyptiacus, a member of the family Spinosauridae within the order Theropoda. First described by Ernst Stromer in 1915, Spinosaurus is widely regarded as one of the largest carnivorous dinosaurs to have existed. Unlike most theropods, it is believed to have been semi-aquatic, adapted to hunting within riverine environments. Its teeth are among its most distinctive features and are commonly found within the Kem Kem Beds.

Morphology and Diagnostic Features
The tooth displays classic Spinosaurid characteristics, including an elongated, conical shape designed for gripping prey rather than slicing. Unlike many theropod teeth, it lacks serrations, instead featuring a smooth enamel surface with fine longitudinal fluting along the crown. The gentle curvature enhances its functional design, allowing for effective capture of slippery prey such as fish. Natural wear patterns may be present, reflecting feeding activity during the animal’s lifetime. The robust structure and mineralised enamel contribute to both durability and aesthetic appeal.

Depositional Environment and Fossilisation
During the Cenomanian stage, the Kem Kem region was a lush and dynamic ecosystem dominated by extensive river systems and floodplains. Spinosaurus occupied a top predator role within this environment, feeding on both aquatic and terrestrial prey. Teeth were frequently shed throughout the animal’s life and could also be lost during feeding. Once deposited in sediment, rapid burial protected the tooth from erosion and decay. Over millions of years, mineral-rich groundwater replaced the organic material, preserving the fossil in remarkable detail.

Condition, Size, and Display Value
At approximately 5 inches in length, this tooth is a substantial and visually striking specimen, ideal for display or as a centrepiece in any fossil collection. Its natural colouration, surface texture, and overall form reflect its geological history and authenticity. The size and preservation make it highly desirable among collectors, educators, and enthusiasts of prehistoric life.
